Thanks Craig.

I'm going to run some tests with PTHD 10.1 and see what the situation is with MTC if the SYnc IO is enabled.

If it's not blocking the use of other devices, I'll cable as suggested above. If it is, I'll have to leave the Sync IO out of the Loop Sync loop (the HD IO manual seems to suggest this is fine), and run studio wordclock to one of my interfaces which can then run as Loop Sync master. Can't think of any reason why this would be inferior to using the Sync IO.

Thanks again

Jules
